Abstract
Es ist ein mit Mikrowellen arbeitendes, auf einem Behälter (3) zu befestigendes Füllstandsmeßgerät vorgesehen mit einem Gehäuse (11), einer stabförmigen in den Behälter (3) weisenden Antenne (7), bei dem die Antenne (7) im Bereich einer Meßgerätbefestigung keine Mikrowellen sendet und empfängt und bei dem die Sendeleistung durch Kondensat oder Feuchtigkeit nicht beeinträchtigt ist. Gemäß einer ersten Lösungsvariante ist die Antenne (7) in dem Gehäuse (11) befestigt ein im Bereich der Meßgerätbefestigung befindlicher Abschnitt der Antenne (7) ist von einer metallischen Hülse (8) umschlossen. Gemäß einer zweiten Lösungsvariante ist an das Gehäuse (11) eine Hülse (8a) angeformt, in der die Antenne (7) befestigt ist. A level measuring device working with microwaves and to be attached to a container (3) is provided with a housing (11), a rod-shaped antenna (7) pointing into the container (3), in which the antenna (7) does not have any in the area of a measuring instrument attachment Microwaves sends and receives and the transmission power is not affected by condensate or moisture. According to a first solution variant, the antenna (7) is fastened in the housing (11). A section of the antenna (7) located in the area of the measuring device fastening is enclosed by a metallic sleeve (8). According to a second variant of the solution, a sleeve (8a) in which the antenna (7) is fastened is formed on the housing (11).
